Bringing police tactics to an infantry fight will get you dead every time. Helicopters have always been sitting ducks dependent largely upon tactics to survive in even the most slightly unfriendly airspace.

It really is a marvel of modern technology that you can have a decent shot at defending yourself from a helicopter with something that costs under $1k and fits in a briefcase.
